What You Need to Cut the Top and/or Bottom off a Closed-head Drum
You need the right drum deheading tool. To choose the right tool, you first need to know if anything is in the drum - for instance, if the drum contains flammable vapors. Also, what is your intention for the drum – to dispose of it as scrap metal or to make it a trash can or other type of usable container?
By using a drum deheading tool you can have a choice of disposing of your drum as scrap metal or turning it into a trash can or another type of usable container.
Warning - using incorrect tools can be dangerous

Why put yourself in harm’s way by using tools not designed to do the job correctly?
You could cut off the drum top with a cutting torch (very dangerous if the drum contains flammable vapors) or use a saws-all (same dangers apply), but either method could take a lot of time and all you would have left is a piece of scrap metal.
